Section 212 Section 212.321  Process Emission Units For Which Construction or Modification Commenced On or After April 14, 1972 a)         Except as further provided in this Part, no person shall cause or allow the emission of particulate matter into the atmosphere in any one hour period from any new process emission unit which, either alone or in combination with the emission of particulate matter from all other similar process emission units for which construction or modification commenced on or after April 14, 1972, at a source or premises, exceeds the allowable emission rates specified in subsection (c) of this Section. b)         Interpolated and extrapolated values of the data in subsection (c) of this Section shall be determined by using the equation: E = A(P B ) where: P = Process weight rate; and E = Allowable emission rate; and, 1)         Up to process weight rates of 408 Mg/hr (450 T/hr): Metric English P Mg/hr T/hr E kg/hr lbs/hr A 1.214 2.54 B 0.534 0.534 2)         For process weight rate greater than or equal to 408 Mg/hr (450 T/hr): Metric English P Mg/hr T/hr E kg/hr lbs/hr A 11.42 24.8 B 0.16 0.16 c)         Limits for Process Emission Units For Which Construction or Modification Commenced On or After April 14, 1972 Metric English P E P E Mg/hr kg/hr T/hr lbs/hr 0.05 0.25 0.05 0.55 0.1 0.29 0.10 0.77 0.2 0.42 0.20 1.10 0.3 0.64 0.30 1.35 0.4 0.74 0.40 1.58 0.5 0.84 0.50 1.75 0.7 1.00 0.75 2.40 0.9 1.15 1.00 2.60 1.8 1.66 2.00 3.70 2.7 2.1 3.00 4.60 3.6 2.4 4.00 5.35 4.5 2.7 5.00 6.00 9. 3.9 10.00 8.70 13. 4.8 15.00 10.80 18. 5.7 20.00 12.50 23. 6.5 25.00 14.00 27. 7.1 30.00 15.60 32. 7.7 35.00 17.00 36. 8.2 40.00 18.20 41. 8.8 45.00 19.20 45. 9.3 50.00 20.50 90. 13.4 100.00 29.50 140. 17.0 150.00 37.00 180. 19.4 200.00 43.00 230. 22. 250.00 48.50 270. 24. 300.00 53.00 320. 26. 350.00 58.00 360. 28. 400.00 62.00 408. 30.1 450.00 66.00 454. 30.4 500.00 67.00 where: P = Process weight rate in metric or T/hr, and E = Allowable emission rate in kg/hr or lbs/hr.
